Remove layout overrides and use tripleo-ci templates instead

As part of [1] and in line with all other tripleo repos lets use
the tripleo-ci templates. The files: and irrelevant-files matches
are moved to tripleo-ci in the depends-on. This leaves only the
undercloud-minion job in the overrides as it isn't covered by the
templates, but updates tags.
